OK....
Might have a brand new 15 gallon zoomed reptile tank with build in screen cover AND a 20 gallon long aquarium.

Throw some ideas at me.

I have had ACF, ADF, Axolotls, and most recently FBTs which are in my 72 gallon bow and breeding like rabbits.

Looking for some easy to obtain species, not too expensive and that cannot live out their lives in these size enclosures.
